Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. Målet med detta projekt var att undersöka hur olika dTreatment of wastewater is crucial for removing any compounds which can have a negative impact on human health and nature before the water is reused or released into nature. Interest in anaerobic treatment of wastewater has increased as it is a good complement to aerobic treatment, and it produces energy in form of methane. The aim of this project was to investigate how different operational para

Stadskartor behövs i städer för bland annat fotgängare och cyklisters behov; Med hjälp av kartorna ska de kunna hitta i staden och kunna ta reda på vad och vilka tjänster som finns i närområdet. Eftersom det produceras många stadskartor så måste produktionen av dem vara relativt billig. Text- och symbolsättning är en del av kartproduktionen. Stadskartor innehåller ofta många texter och symboler soAutomatic label placement on maps has been studied for many decades. This study has addressed the problem of automatic label placement by applying the labelling library PAL for labelling static, large scale city maps which the map company T-Kartor produces. Label placement rules were acquired from an interview with a person from the company. These rules were then applied on the labelling. The aim

Varannan tugga i Sverige är importerad från alla världens hörn och det enda vi är helt självförsörjande på är spannmål, socker och morötter. I en krissituation där vi inte längre har tillgång till importerade livsmedel kanske vi får leva på enbart morotskaka om vi inte ökar vår livsmedelsproduktion. Klimatförändringen kommer att påverka hela världen och ändra förutsättningar som vi idag mer eller Only 50 percent of Swedish food supply comes from domestic production, which creates a high dependency on an international trade to import foods. This leads to a high vulnerability within the food system. In order to secure food supply in times of crisis Sweden must increase its food production. According to climate research, future climate will be characterized by a higher rate of extreme weather

Pluviala översvämningar inträffar när intensiteten av ett regn överskrider markens förmåga att infiltrera, vilket resulterar i att vattnet istället ansamlas på ytan. Tillräckligt mycket vatten på samma yta leder som bekant till översvämning. Ett typexempel är när korta intensiva regn faller över urbana områden där ytor som asfalt förhindrar infiltrering. Mängden och intensiteten av denna typ av övThe number and impacts of pluvial floods are likely to increase with the growth of our cities and as extreme weather is anticipated to intensify with climate change. Im- proved preparedness is needed which may be attained owing to recent development of high-resolution hydro-meteorological observations and forecasts as well as geographical data. This paper investigates the capacity of the HYPE mode

Denna uppsats behandlar frågan om hur EU:s konkurrensrätt förhåller sig till rättsprincipen ne bis in idem. I och med att Förordning 1/2003 trädde i kraft 2004 så ändrades reglerna om tillämpning av EU:s konkurrensregler i grunden. I det nya moderniserade tillämpningssystemet på konkurrensrättens område så delar Kommissionen behörigheten att tillämpa EU:s konkurrensregler med nationella konkurrensThis paper addresses how the principle of ne bis in idem relates to the enforcement of EU competition law. Regulation 1/2003 came into force in 2004 and with this the enforcement system of EU competition law that had been in place for over 40 years was fundamentally reformed. Under the new modernized enforcement system of the EU competition rules, national competition authorities (NCAs) and nation

Populärvetenskaplig sammanfattning: Sölvesborgs kommun i västra Blekinge ser med viss oro på sin framtida vattenförsörjning. Denna baseras sig till allra största del på grundvatten som tas från vattenförande sedimentberggrund liggande ca 40-70 m under markytan. Att detta grundvatten har god kvalitet är vitalt för kommunen. Tidigare har det förekommit problem med förhöjda salthalter (NaCl) i grundvThe municipality of Sölvesborg, western Blekinge, is somewhat concerned about their future water supply. Problems with salty groundwater have occurred, and two municipal groundwater wells has been closed because of too high chloride ion concentrations. High chloride ion concentrations gives the water a salty, unpleasant taste and has a corroding effect on metals. This investigation has been carrie

This thesis examines EU’s adoption of a human security approach and the extent to which it has been part of crisis management discourse as well as practice in the Sahel region of Africa. It tells the story of a maturing process for a core approach in EU security policy; that is, the story of human security and how the concept has evolved from a state of innocence to gradual experience and adolesc

High quality III-V semiconductors on silicon substrate can make for significant progress in gate electrostatics and optoelectronic devices. Indium antimonide with its inviting properties can play a key role to further facilitate devise integration. But the question is, is it possible to obtain high quality III-V semiconductors on low cost silicon and still be able to manufacture it at large scale?

Förhållanden i och runt Segeå i Skåne har undersökts teoretiskt för att kartlägga möjligheten att främja förekomsten av stormusslor där. Ån är i högsta grad påverkad av det odlingslandskap som omger den, med övergödning som en av följderna, och är ofta väldigt grumlig. Musslor är filtrerare och livnär sig på växtplakton, som bildas i större utsträckning i näringsrika akvatiska miljöer. VäxtplanktoIn this study Segeå has been valued to consider possibilities of increasing the amount of mussels as effective filterers in the creek. The purpose would be to reduce high levels of nitrogen and phosphorus; a result of the agriculture in the area. Mussels filtrate water in search for nutrition, and bind nitrogen and phosphorus in their bodies. Using rapports from mussel projects, contacts on count

This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. This thesis considers such a system, where the smart phone contains accelerometer and gyroscope sensors

Dockless bike-sharing is growing in many cities around the globe. At the same time issues related to this type of urban mobility such as illegal or improper parking behavior are becoming more frequent. The implementation of parking zones delineated by geofences has been discussed as a possible solution for these issues. This master thesis project aims to develop a GIS-based multi-criteria analysis

An increased proportion of trips made by bike is important part of a more sustainable transportation system. It provides benefits both at an individual and societal level – especially when replacing trips that would otherwise have been made by car. To get an understanding of what influences cycling, a statistical analysis is carried out that shows links between socio-economic factors, the physical

Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. The first network uses the Morlet wavelet transform to achieve adaptable f

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry is not adequate for the determination of some potentially hazardous trace elements, such as Cd, Cu, Ni and Pb at low concentration in PM2.5 atmospheric aerosol particles. Therefore, a method has been developed for the determination of these elements in atmospheric aerosol particles using high-resolution continuum source graphite furnace ato
